What do V shaped contour lines indicate the presence of? Widely spaced contour lines indicate that the land is relatively level. A contour line that bends to form a V shape indicates a valley. The bend in the V points toward the higher end of the valley; this V points upstream, or in the direction […]

Do colleges allow test retakes?
Do colleges allow test retakes? Partial retakes are permitted by others if there are certain sections a student performs poorly on, and still others allow students to retake any exam at any time, and use the higher grade as their final score. Why is teaching to the test bad? In a research paper published in […]
What is the purpose of graphite?
What is the purpose of graphite? Graphite is used in pencils and lubricants. It is a good conductor of heat and electricity. Its high conductivity makes it useful in electronic products such as electrodes, batteries, and solar panels. What are the properties of graphite and diamond? Diamond Graphite The geometry is tetrahedral. The geometry is […]
Why is sound not heard in space?
What are two factors that help determine the strength of an electric field at any given point in space?
What are two factors that help determine the strength of an electric field at any given point in space? The new formula for electric field strength (shown inside the box) expresses the field strength in terms of the two variables that affect it. The electric field strength is dependent upon the quantity of charge on […]
What will happen if there is no convection current in the asthenosphere?
What will happen if there is no convection current in the asthenosphere? If for some reason convection stopped, air would not circulate, and weather would stop. Air wouldn’t flow over the waters, suck up moisture and then rain it out on land. Without this rain, all plants and crops would die. How does the process […]
What is the difference in elevation between two side by side contour lines called?
What is the difference in elevation between two side by side contour lines called? A contour interval is the difference in elevation between two contour lines that are side by side. Remember that a contour interval is not the distance between the two lines – to get the distance you need to use the map […]
Can the Y intercept change?
Can the Y intercept change? In general, when a line shifts in such a way that it maintains the same steepness as the original line, but moves up or down, or to the right or left, the y-intercept changes while the slope remained the same. If the line changes steepness, the slope must have changed. […]
